RELEASE: FSI Pages JS Build 17.06.14

changed: Listeners which are added via addListener(), remain valid when changeConfig() is called (Beforehand they were deleted when changeConfig() was called, just like the listeners which are defined via config files)

changed: the onInitFailed listener now returns a string with a reason why the object could not be initialized, and is now defined in a ifferent way: onInitFailed(strReason)
